GEORGE A. HINES, OF BRATTLEBOROUGH, VERMONT, ASSIGNOR OF ONE-HALF HIS RIGHT TO J OHN F. VINTON, OF SAME PLACE.

IMPROVEMENT IN RAILROAD-CAR VENTILATORS.

Specification forming part of Letters Patent No. 119,982, dated October 17, 1871.

To all whom it may concern:

Be it known that I, GEORGE A. HINES, of Brattleborough, in the county of Windham and State of Vermont, have invented a new and Improved Method of Ventilation, of which the following is a specification:

My invention relates to the creating ofa draught or current for the purpose of removing vitiated air from any transient or permanent habitation, and in the following description I have taken its application to a railroad car for its illustration.

Figure l is a side elevation embodying my in vention. Fig. 2 is a end elevation of the same. Fig. 3 is a vertical transverse section, showing those parts which are to the left of the line It T, Fig. 2. Fig. 4 is a horizontal transverse section, showing the parts which lie under the line L M, Fig. 1.

A A A A is the wood-work of the deck of a car. B, Fig. 4, is the cell or opening through A A. 0, Figs. 2, 3, and 4, is the ventilating-plate having minute apertures cut through it vertical ly. D, Figs. 1, 2, and 4, is the shield for protecting the plate 0 from the weather. E E E E is the clamping plate or frame, which is secured on the outside of the wood-work A A, &c., and holds firmly to it the cell 13, the ventilating-plate O, and the shield D by means of lips turned out on their edges and coming under said plate. F F, Figs. 2 and 4, is the covering or finish plate or frame, around the inner edge of the cell B. It is screwed onto the inside of the wood-work A A, and to it is hung the door f.- G, Figs 3, is the ingress reservoir. 9, Figs. 2 and 3, is the line of the bottom surface of G. H H, Fig. 3, are ingress apertures. h h, Fig. 3, are concave deflecting surfaces. h h, Fig. 3, are inclined deflecting surfaces. I I, Figs. 2 and 3, are the ends of the reservoir G. The ventilating-plate O is turned down at its sides sufficient to bring its surface out beyond the clamping-frame E, as seen in Fig. 2. The bottom of the shield D is made a little lower than the bottom edge of the plate 0, as seen at d, Fig. 2, in order to conduct away any Water which may come in under the shield.

The operation is as follows: The current of air across the surface of the ventilating plate 0, caused by the rapid motion of the car, creates a draught from the inside of the car out and carries with it the vitiated air; the air also passes up the ingress apertures H H and over the concave plates or surfaces h h into the reservoir G, as shown by the direction of the arrows, Fig. 3, from whence it passes through the apertures of the upper portion of the plate 0 into the inside of the car to restore the loss. The cinders and dust are turned from the reservoir G by the deflecting surfaces h h and h h, and the surfaces I I. The constant draught out and the small ness of the apertures prevent dust and cinders from entering the ventilating-plate G.

What I claim as my invention, and desire to secure by Letters Patent, is

l. The ventilating-plate 0 combined with hood D, and so divided longitudinally as to aflord an induction and eduction-draught, substantially as shown.

2. The induction-ports H, in combination with hood D and chamber Gor their equivalents, substantially as shown.

3. The deflecting surfaces 71., h ,and I, or their equivalents, in the combination shown and described.

4. The combination, with the foregoing ventilating apparatus, of the door f or its equivalent.

GEORGE A. HINES.
